I have a user on SQA stack exchange that shows as having 5 reputation. Their graph, their profile, everything.

Their profile shows four questions and two answers. All have 0 up and 0 down votes. Three of the questions have accepted answers. That should yield 6 reputation. One of the answers was flagged as accepted. This should yield an additional 15.

The initial 1 reputation, plus 6 from questions, plus 15 from the answer should be 22 rep. But the user only has 5. Is this a bug?
